We found the divisors of 721, 533, 548, 915 . The biggest common divisior number is the GCD number.
So the Greatest Common Divisior 721, 533, 548, 915 is 1.

Therefore, GCD of numbers 721, 533, 548, 915 is 1

Given Input Data is 721, 533, 548, 915

Make a list of Prime Factors of all the given numbers initially

Prime Factorization of 721 is 7 x 103

Prime Factorization of 533 is 13 x 41

Prime Factorization of 548 is 2 x 2 x 137

Prime Factorization of 915 is 3 x 5 x 61

The above numbers do not have any common prime factor. So GCD is 1

Step1:

Let's calculate the GCD of first two numbers

The formula of GCD is GCD(a, b) = ( a x b) / LCM(a, b)

LCM(721, 533) = 384293

GCD(721, 533) = ( 721 x 533 ) / 384293

GCD(721, 533) = 384293 / 384293

GCD(721, 533) = 1

Step2:

Here we consider the GCD from the above i.e. 1 as first number and the next as 548

The formula of GCD is GCD(a, b) = ( a x b) / LCM(a, b)

LCM(1, 548) = 548

GCD(1, 548) = ( 1 x 548 ) / 548

GCD(1, 548) = 548 / 548

GCD(1, 548) = 1

Step3:

Here we consider the GCD from the above i.e. 1 as first number and the next as 915

The formula of GCD is GCD(a, b) = ( a x b) / LCM(a, b)

LCM(1, 915) = 915

GCD(1, 915) = ( 1 x 915 ) / 915

GCD(1, 915) = 915 / 915

GCD(1, 915) = 1

GCD of 721, 533, 548, 915 is 1
